COMBINED FILTER AND PURIFIER.

SPECIFICATION forming part of Letters Patent No. 585,281, dated J' une29, 1897. Application filed August 12, 1896. SerialNo. 602,520. (Nomodel.)

To a/ZZ whom, t may concern.-

Be it known that I, THOMAS D. MCCLARY, a

i citizen of the United States, residing at Washington, in the Districtof Columbia, have invented new and useful Improvements in a CombinedFilter and Purifier, of which the following is a specification.

This invention relates to a combined water filter and purifier, whichmay be connected with the service-pipe of a water-main in such manner asto automatically receive therefrom the water to be filtered.

The object of the invention is to provide a .r ing medium, such astripoli or unglazed earthenware, and then through a secondaryfilteringchamber containing charcoal or other form of carbon.

It is well known that water that is rendered mechanically pure bymechanical filtration is not chemically pure and that it is necessary inorder to remove or destroy all organic matter and deleterious gases insolution to subject the said water to a second or chemical filtration.To this end I employin connection with the filtering-chamber containingthe tripoli or unglazed earthenware diaphragm a secondaryfiltering-chamber containing charcoal, sand, and other filteringmaterial, also a reservoir for the filtered water, the said parts beingarranged in such a manner that the water which filters through thediaphragm passes thence directly into and through the material containedin the secondary lterin gchamber, from whence it is delivered in athoroughly clear and purified condition into the filtered-waterreservoir for use as occasion may require.

The invention also provides means for automatically regulating theinflow of wat-er to be filtered as well as to facilitate the cleansingor renewing of the filtering material when it becomes clogged oruseless.

The above-mentioned objects are attained by the means illustrated in theaccompanying drawings, in which Figure 1 is a perspective view of myimproved filtering apparatus in position. for use.

Fig. 2 is a vertical transverse section of same. Fig. 3 is a horizontalcross-section through the line m of Fig. 2. Fig. 4 is a horizontalcross-section through the line x of Fig. 2; 55 Fig. 5, a horizontalsection taken on the line also of Fig. 2; and Fig. 6, a verticaltransverse section of the purifying receptacle.

Referring to the drawings, the figure 1 indicates a filteringchamber,which is con- 6o structed, preferably, of metal and of any desiredshape. In the present instance it is represented in rectangular formwith a contracted top and a dome-shaped cover 2, having an air-tightjoint between same, as indicated at 3. Within the said chamber and itscover is located a bellshaped chamber 4, the said chamber beingsuspended by means of a screw stem or rod 5, passing through astuffing-box 6, which is securely packed, so 7o as to be water-tight.The stem at its outerV end is provided with a knob 7, by means of whichit may be manipulated to raise or lower the chamber 4.

The mouth or lower part of the chamber 4 75 is providedwith a porousfiltering diaphragm 8, which may be of any suitable material. The saiddiaphragm is provided with a central aperture having a suitable packing9, through which extends the upper end of a 8o pipe 10, upon which thediaphragm is adapted to be moved vertically for the purpose hereinafterdescribed.

The lower end of the pipe 10 is screwed or otherwise securely fitted inbottom oit the 8 5 chamber 1, so as to connect, by adownwardlyprojecting pipe 11 and thimble-joint 12, with the top of asecondary filtering-chamber 13, which is provided with a removablereceptacle 14, adapted to rest on an inwardly-projecting 9o ange 15 ofthe aforesaid chamber, which is also detachable, being held by a sideprojecting pin 15 and slotted base-ring 15, forming part of or securedto the top of the filteredwater receptacle. All the parts are made tightby suitable packing.

The removable receptacle 14 is divided by a vertical partition 16,having perforations 17 in the lower part thereof, forming cornmunicationbetween the two compartments. roo One of the said compartments isprovided lwith a funnel-shaped mouth 18, through which the water fromthe upper filter is received, while the other compartment is providedwith an overflow-pipe 19, by which the filtered water is conveyedthrough the bottom of the receptacle and allowed to drip into thefilteredwater reservoir 2O below same.

The reeeiving-compartment of the aforesaid receptacle is filled withgood-sized lumps of charcoal or other filtering material, while thesecond compartment has the lower part thereof packed with similarmaterial, a strata of fine sand above same, a-nd a layer of pebblesthereon.

The filtered-water reservoir 2O is preferably surrounded by anice-compartment, as shown at 21, having double walls packed withnon-conductor material and provided at its top with suitable openingsand covers for the introduction of the ice. As no claim is made to thisfeature, it is not deemed necessary to herein further explain.

The filtered water is withdrawn from the reservoir through aservice-pipe and faucet, (shown at 22.)

The filtering-chamber 1 is supported above the filtered-water reservoirby columns 23 24 25 2G, two of which are open throughout their wholelength, so as to serve, respectively, as inlet and outlet pipes. Theends of all the columns are outwardly screw-threaded, so that theirupper ends may fit into screwsockets formed in the bottom of thefilteringchamber 1, the lower ends of said columns being fitted inapertures in the top wall of the ice-compartment or filtered-waterreceptacle and securely held therein by threaded nuts or sleeves, asshown at 27 and 28 in Fig. 2, the joints at each end of the columnsbeing made perfectly tight by washers or packing, as required in suchcases.

The nuts or sleeves 27 28 are made sufficiently long to receive theupper threaded ends of the inlet and outlet pipes 29 30, the

Y latter formed in two sections and having in its upper section a valve3l, to the stem of which is secured a lever 32, having a fioat 33,secured to the outer end thereof, so that the said valve shall beoperated by the rising or falling of the water contained in thefilteredwater receptacle. The lever is pivotally connected with a rod34, which is adapted to operate in an aperture in the top of the cooleror filtered-water receptacle. The upper part of this rod isscrew-threaded and provided with a nut 35, by which the fall of thefloat is limited.

The inlet and outlet pipes 29 30 are each provided with stop-cocks, asat 36 37, so as to regulate the flow of water through same.

The numeral 3S indicates two or more arms secured to a hub 39, locatedin the filteringchamber 1 and adapted to turn upon the pipe 10. The saidhub is provided with a miter gear-wheel 40, which intermeshes with asimilar miter gear-wheel 41, mounted on a rod 42, which passes through astuffing-box 43, secured to the wall of the chamber 1. The said rod issupported near its inner end by a bearing 44 and is provided at itsouter end with a milled but-ton 45, by means of which it may be turnedto operate the arms 3S before mentioned. These arms are provided withbrushes 45 and rubber strips 4o', upon which the porous diaphragm, maybe brought to bear, so that when the arms are turned andthe chamber 4,with its porous diaphragm, depressed the brushes will scrub and cleanthe lower surface of the diaphragm. rlhe rubber strips 46 serve to limitthe pressure on the said brushes, and thus prevent injury to same.

A draining-faucet 4G is fitted in the bottom of the ice-compartment, orfiltered-water receptacle should the ice-compartment be omitted, so thatthe same maybe thoroughly drained when necessary.

The apparatus is mounted on a suitable table or stand 4G, which ispreferably provided with closed sides, so as to4 hide from view thepipes contained therein.

The operation of my invention is as follows: The parts of the apparatusbeing properly assembled and mounted the water firstY enters thechamberl through the pipe 30 and column 23, then passes upward throughtheV porous diaphragm, then downwardly through the pipe 10 into thesecondary filter-receptacle 14, then through the filtering materialcontained therein and down through the overflow-pipe 10 into thefiltered-water receptacle 20, where it is collected and stored for use.

W'hen necessary to cleansel or repack the secondary filter, the same isremoved by unscrewing the thimble-joint 12 and then slightly turning thesaid receptacle, so as to free it from the base-ring 15".

To clean the surface of the filtering-diaphragm, open the outlet-valve36 at the lower part of the pipe 29, permitting the water to passthrough the lower part ot the filteringchamber l, under full pressure,then rotate the brushes, by means of the milled button 45, upon thesurface of the .filtering-diaphragm, thereby removing therefrom thelayer of foreign matter which has formed therein, which, on beingreleased, will be taken up by the current and be carried away by theoutlet-pipe 2).

Having t-hus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination in a filtering apparatus, of a filtering-chamberconnected to a suitable service-pipe, a movable chamber located in saidfiltering-chamber and means for moving it vertically, the said chamberbeing provided with a porous diaphragm having a packed central aperturethrough which the outletwater passes, the brush-arms and brushes, andmeans substantially as described, whereby the said brushes maybeoperated to scrub the diaphragm, as set forth.
